First thing is to select the right network adapter in virtual machine settings. Select NAT in the network adapter box and then select correct adapter type.

2 Figure 19: Network Adapter settings The screenshot above was taken from virtual box s network setting page but it doesn t matter whichever virtual machine you select the settings are more or less the same. You don t have to do anything in specific to configure the DNS but just in case if something goes wrong you can refer to this section to get help. For example, you are unable to connect to the Internet after installing AD and DNS roles. Following are few tips that will help you get connected to the Internet. 1. Did you reboot your server after installing new roles? If not, the first thing you need to do is reboot your server. 2. Check your Network and Sharing Center. It will show you which part is malfunctioning.

3 Figure 20: Network and Sharing Center The above image has three main objects. One is the computer. Second is the domain name and third is the Internet. If your computer is not joined to your domain, the first link will be shown as broken. If your computer is joined to your domain but domain is not connected to the Internet, the second link will be shown as broken and in some cases, both links will be broken so you will need to fix both of them one by one. Easiest way of resolving these issues is to double click the troublesome link and Windows will resolve the issue automatically for you. Sometimes, Windows will fail in resolving it and you will be left with only one option and that is to set It up yourself. 3. Open command prompt and type ipconfig /all. It will show you some settings. Note down IPv4 Address and Subnet Mask values. Figure 21: IP settings 4. In Network and Sharing Center, click Change adapter settings.

Select Use the following IP address option. Figure 23: IPv4 Properties 8. In IP Address, type the address of the client computer (copied from command prompt). 9. In Subnet Mask, type the subnet mask of the domain controller (copied from command prompt). 10. In Default gateway, type the address of the default gateway of the domain controller. If you don t know the address, type for now.

There will be two IPs, one for preferred DNS server and the other for Alternate DNS Server. 13. Come back to your guest OS (step 9) and enter values copied from host OS in the Preferred DNS Server and Alternate DNS Server. 14. Click OK and then OK. 15. Now go back to Network and Sharing Center and see if the problem has been fixed. If not, it will show you red X to indicate the problem. Continue with the following steps if the problem has not been fixed yet otherwise stop here. 16. Open Server Manager. Expand DNS Server node, expand DNS node, Expand Forward Lookup Zones and then click node that has your domain as its name. In the right side pane, you will see some entries that will have IP in the Data column. Delete these entries. 17. Go back to Network and Sharing Center and double-click the red X. This will start Windows diagnostics and will automatically fix the problem. Basically what Windows does is that it enables DHCP on the LAN. You can do that manually also but if for some reason Windows does not pick up the changes you make you can use Windows to make the changes for you. After Windows has enabled DHCP, your virtual machine will get connected to the Internet. I am assuming that you are using dynamically generated IP and not static one. Figure 24: View active networks To verify that DHCP has been enabled, open properties window of your LAN connection. Click Internet Protocol Version 4 (TCP/IPv4) and then click Properties.

6 Click Advanced button. In IP address column, you will see DHCP Enabled listed. To read more, download Installing and Configuring SharePoint nd Edition from the following link:
